Performance Improvements! (v1.1.2)

Back with another update! In this one, I tried to improve performance and stability of the game overall. Here's the notes:

• Fixed 'out of memory' crashes when using a lot of fast-firing weapons over longer play sessions
• Reduced the total file size of the game by over half
• Made lots of small tweaks to the code that should help the performance of the game overall
• Did some balancing tweaks around shooting weapons

Thanks for your continued support and feedback, it means so much to me to hear everyone enjoying the game and reporting issues!
